"Apple vs. Samsung initially ended with a billion-dollar verdict in favor of Apple, but there have been plenty of wrinkles since. This week brought about another, as Nokia filed an amicus brief on behalf of Apple, Inc. in the US Court of Appeals for the Federal Circuit. In the brief filed Monday, Nokia asked the court to permit permanent injunctions on the sale of Samsung phones that were found to infringe Apple's patents." In the meantime, the latest comScore figures for the US show that Windows Phone's market share actually declined during the launch of Windows Phone 8. It's pretty clear that, combined with the disappointing quarterly results for Nokia, the company is setting itself up for the future. In this future, Nokia's patent portfolio is worth more than their actual phone business, and as such, Nokia can't do anything but support Apple in this case, else the value of their portfolio goes down.
